T 0 all whom it may concern:

Be it known that I, WINFORD L. ENG- HAUSER, a citizen of the United States of America, and resident of Winslow Park, county of Hamilton, State of Ohio, have invented certain new and useful Improvements in Cleaning, Plating, Drying, and Burnishing Machines, of which the following is a specification.

This invention relates to improvements in a combined mechanical cleaning, plating, drying and burnishing machine.

An object of my invention is to produce a single machine for use in all of the operations above mentioned, in which it is unnecessary to remove the work from the machine in carrying it through the successive operations.

A further object is to produce a machine of the class described, which may be carried readily from place to place and supported on tanks, frame work and other suitable supports used in the various operations above mentioned.

A further object is to produce a machine of the character described, having a receptacle which may be moved to a position in which its interior is rendered accessible for the placing therein of articles to be cleaned, plated, dried or burnished, and which may be moved to a position for emptying the contents thereof without having to reach .into the receptacle in order to remove the articles located therein.

These and other objects are attained in the machine described in the following specification and illustrated in the accompanying drawings, in which;

Figure 1 is a plan view of a machine embodying my invention, mounted on a tank adapted to hold a plating solution. Fig. 2 is a side elevation of a machine embodying my invention, the receptacle and tank being shown in longitudinal section. Fig. 3 is a transverse sectional view taken on line 33 of Fig. 1. Fig. 4 is a transverse sectional view of the machine taken on the line 44 of Fig. 1. Fig. 5 is a fragmental sectional view of the means for rotatively mounting the receptacle at its driving end, of rotatively connecting it with its driving mechanism, and of electrically connecting its interior with a pole of the circuit employed in the plating operation. Figs. 6 and 7 are fragmental sectional views of de tails of construction of the receptacle, showing modified forms thereof. Fig. 8 is a detail fragmental perspective View of one of the staves of the receptacle.

The machine embodying my invention consists of a cylindrical receptacle 8 rotatively mounted at its ends in brackets or hangers 9 and 10 secured to and forming a portion of a rocking frame 11 located above the receptacle. The frame 11 is provided at points intermediate of its ends and preferably centrally thereof with bearings 12 which cooperate with bearings 13 secured to a stationary frame 141, in rotatively mounting the frame 11 thereon. The frame 14 is provided with outwardly extending arms or handles 15, 16, 17 and 18 which engage the sides of the tank or framework upon which the machine is supported and which may be removably mounted in brackets 19 secured to the edges of the tank or framework as shown in Figs. 1, 2 and 3. The receptacle is provided with a removable cover 20 at its end adjacent to the hanger 9, and is adapted to be rotated by means of driving mechanism, 21 suitably connected with the opposite end of the receptacle and mounted in bearings 22 and 23 formed in the bracket 10 and a bracket 24, respectively, which rotatively mount a shaft 25 extending from a driving shaft 26 extending transversely of the machine and provided with a worm 27 which meshes with a worm gear 28 mounted on the shaft 25. Suitable means for rotating the shaft 26, such as bevel gears 29, are provided, these gears in turn communicating with any suitable dri ing mechanism operatively connected with the drive shaft 30. The means for driving the shaft 30 preferably consists of an electric motor mounted on the frame 14.

The receptacle is constructed of a series of staves 31, preferably of nonconductive material. and provided at intervals with elongated notches 32 located at opposite sides of the staves. portions 33 between the notches being left the full width of each stave, so that when the staves are assembled a series of slots 34 are formed between a series of annular imperforate portions 35 formed by the unnot'ched portions'33 of the staves. The driving end of the receptacle, which end is not removable is formed of two disks of nonconductive material. 36 and 37, the disks being turned with relation to one another ing train 21.

so that the fiber in one disk lies at right angles to the fiber in the adjacent disk. Surrounding the staves and holding them together in cylindrical formation are a series of hoops 38 which are preferably of metal and bind the staves together in much the same manner that an ordinary barrel is constructed. The hoop at the open end of the receptacle is preferably of cast metal construction and is provided with a semi-circular bail-like member or bracket 39 which is provided with a bearing 40 coaxial with the axis of the receptacle and journaled upon a pivot pin 41 secured in the lower end 42 of the hanger 9. This bail-like member 39 is also provided with lugs 43 located adjacent to the hoop portion 38 and adapted to be engaged by the ends of a spring 44 secured to the cover or lid 20 adapted to close the end of the receptacle, the. engagement of the ends of the spring with the pins, holding the cover against displacement from the end of the receptacle. At the opposite end of the receptacle, the means employed for rotatively mounting and supporting it at this end consists of a ring 46 secured concentrically with the periphery of the receptacle and provided with a series of pins 47, 48 and 49, the pins entering openingsin the web of a gear 50 forming one of the driv- The gear= 50 is rotatively mounted on a metal sleeve 51 secured in the lower end 52 of the bracket 10. Thus the pins 47, 48 and 49 support the entire weight of the receptacle and its contents at its driving end.

In order to electrically connect the objects being plated, with the electro-plating circuit, a series of metal rings 53 are spaced along the interior surface of the receptacle and embedded in the material of the staves in the manner shown in Fig. 2 and at the points where the unnotched portions 33 form the annular imperforate portions 35 of the receptacle. These rings are electrically connected together by means of a strip of metal 54 extending longitudinally of the receptacle. This strip of metal is terminated at the open end of the receptacle and at the bottom or closed end is brought to a point adjacent to the axis thereof, by extending the strip between the layers 36 and 37 of the bottom. To this'inner central end of the strip 54 is electrically connected a collar or plate 55 which has a boss 56 extending therethrough and through the outer portion 37 of the bottom, the plate 55 being embedded in the material of the portion 36 of the bottom. The boss 56 is provided with a hemispherical recess adapted to receive the hemispherical end 57 of an electric contact pin 58. This pin is located within a sleeve 59 of hard rubber, fiber, or other suitable insulating material, which at its inner end is provided with a screw threaded flanged collar 60 of insulating material, mounted on the sleeve 59 and surrounding the portion of the hemispherical end 57, which extends beyond the boss 56. The extension 61 of the flanged collar 60 is provided with an additional insulating collar 62 which fits over the extension 61 and engages the collar 60 and is secured to the portion 37 of the bottom in some suitable manner such as disclosed in Fig. 5 of the drawings. Between the collar 60 and the drive gear 50 is a short metal collar 63. This collar is securely mounted on the metal sleeve 51 secured in the lower end 52 of the bracket 10, for the purpose of reducing the friction of rotation created by the gear 50 upon the insulating collar 60. The insulating sleeve 59 extends beyond the outer end of the metal sleeve 51 and is screw threaded to receive acap 64 of insulating material having a reduced opening in its outer end, through which passes the wire 65 communicating electric current to the rings 53 of the receptacle. This wire is secured in any suitable manner to the pin 57, as for example by being soldered thereto, and is provided with an insulating covering 66 of rubber or other suitable insulating material. This wire is brought back over the frame 11 and is given a few turns around the axial pin thereof in order that the frame 11 may be turned to bring the receptacle to the filling or emptying positions without subjecting the wire to undue tension.

In order to drive the gear 50 I have so constructed the train of gears 21 that they may be brought to such a position as to rotate the drum in either direction for purposes hereinafter to be more fully set forth. In order to drive the receptacle in first one direction and then in the other direction the train of gears 21 has been divided into a series of gears 67, 68 and 69 mounted on an arm 70 of a gear changing lever 71, and a series of gears embodying the gear 67 and an additional gear 72 mounted on an arm 73 of the lever 71, either gear 69 or 72 being adapted to engage the driving gear 50 of the receptacle, when the gear changing lever 71 is moved to the proper points on quadrant 74.

The quadrant 74 is constructed as a separate element of the frame 11 and is secured in the position shown thereon in Figs. 1 and 2, notches being provided in the quadrant for holding the lever 71 in its proper position to retain either of the gears 69 or 72 in engagement with the driving gear 50. The arms 70 and 73 carrying the respective trains of gears, are formed integrally with a sleeve 75 rotatively mounted on the drive shaft 25 carrying the gear 67. As shown in Fig. 4, movement of the lever 71 to the position shown in this figure, will cause gear 50 to rotate in the direction of the arrow and thus rotate the receptacle in the same direction, and by moving the lever 71 to the opposite position to disengage the gears 50 and 72, will bring the gear 69 into engagement with the gear 50 and rotate the gear and the receptacle in a direction opposite to that indicated by the arrow.

The pivotal mounting of the receptaclecarrying frame is accomplished in the following manner. The journal blocks 12 located on the longitudinally extending members 76 and 77 of the swinging frame 11, are provided with annularly outwardly extending flanges 7 8, which engage the surfaces of inwardly extending bosses 79 formed on the bearings 30 located on the longitudinally extending members 80 and 81 of the stationary frame 14. This construction pivotally mounts the swinging frame 11 with relation to the stationary frame 14. In order however, to control the swinging of the frame and the receptacle the bearing 12 located on the side opposite the bevel drive gears, is provided with a shaft 82 which is secured in the bearing 12 and rotatively mounted in the bearing 13. The end of this shaft extends beyond the member 80 of the frame 14 and is provided with a worm gear 83 mounted on and secured thereto, the worm gear meshing with a worm 84 secured to a short shaft 85 journaled in a bracket 86 secured to the frame member 80 adjacent to the bearing 13. At the upper end of the shaft 85 is secured a hand wheel 87. By rotating this hand wheel the gears 84: and 83 are rotated and by m ans of the shaft 82 the rocking frame 11 is moved to a position in which the receptacle is located in inclined positions for filling or emptying. In addition to the shaft 82, the transversely extending drive shaft 26 carrying the worm 27 is rotatively mounted in the bearings 12 and the opposite bearing 13, one end of the shaft being provided with one of the beveled gears 29, the construction being shown in section in Fig. 3.

Vhen the machine is to be employed in the plating operation such as disclosed in the drawings, the usual plates 88 of metal to lie-deposited on the articles located in the container, are suspended in the plating solution from the usual rods 89 extending from one end to the opposite end of the tank and located on each side thereof. The opposite terminal of the circuit, from the terminal connected with the wire 65, is then connected with the bars 89 suspending the plates 88.

Animportant feature of the construction of the receptacle as disclosed in Fig. 3, consists in so forming the staves that the slots 34 extend in directions substantially tangent to the circle formed by the inner surface of the receptacle. These slots because of their tangentially extending directions, extend from their inner ends to their outer ends in diverging directions with relation to one another. The purpose of this construction is to aid in the circulation of the plating solution through the receptacle and consequently over the articles located in the receptacle when the receptacle is rotated in the direction indicated by the arrow in Fig. 3. This feature of construction is also desirable when the machine is used for cleaning or drying the articles located in the receptacle. For example, when used in the drying operation, sawdust is placed in the receptacle with the articles and the receptacle is rotated in the direction indicated by the arrow in Fig. 3. In this direction of rotation the sawdust is retained within the receptacle and the articles are tumbled over one another together with the sawdust, until all moisture, oil, etc., existing on the surfaces of the articles located within the receptacle have been absorbed. After this operation is complete, the rotation of the receptacle is reversed by bringing the gear 72 into mesh with the gear 50 as shown in Fig. 4:. This causes the sawdust to be sifted through the slots 34 by moving the slots in a direction such as to direct it from the interior of the receptacle. In this manner the work located therein is thoroughly cleaned and all particles of sawdust removed. I have found that at times it is desirable to vary the construction by changing the shape of the slots to a certain extent, especially when the articles located in the receptacle, are of such dimensions as to be liable to slip through the slots during the sifting operation. This is especially true in the plating of thin sheets of metal, it being an easy matter for the sheets to slip through the slots. To overcome this objection it may be desirable to construct slots in such a manner that they have either of the shapes disclosed in Figs. 6 and 7, in order to break up the straight line formation thereof and to arrest the movement of the sheets should they have entered them. Of course, any variation of the shapes herein illustrated may be employed without deviating from the principle 'of operation thereof.
